Low Carbon Benefits of Corn Ethanol
The Renewable Fuel Standard has successfully driven the production and use of low carbon fuels in the U.S. transportation fleet. Corn ethanol has replaced 10 percent of climate change causing petroleum. The RFS was enacted, in part, to drive innovation and the production of low carbon biofuels that reduce greenhouse gas (GHG) emissions by at least 50 percent and more than petroleum - so called "advanced biofuels."
This White Paper walks through the current state of science as it relates to the lifecycle GHG emissions of corn ethanol and makes recommendations for updating lifecycle modeling which is used to inform low carbon policy decisions.
